Set Motor Speed Neje 3

Hello friends,
I bought a Neje 3 with a 7W module.
However, my neje master 2 had an option to increase the Set Motor Speed.
How can I increase the Set Motor Speed? Does anyone know what values I can put here?
Help me. The laser engraves very slowly and I want it to be faster.

Adjust the speed here

That’s for the burner. Not for engine speed.
